6 FAQs about [Polypropylene film capacitor characteristic curve]

What are metallized polypropylene film capacitors?

Does frequency affect the capacitance of polypropylene capacitors?

What is the temperature coefficient of a polypropylene capacitor?

The temperature coefficient is essentially determined by the properties of the dielectric, the ca-pacitor construction and the manufacturing parameters. Polypropylene capacitors have negative temperature coefficients, polyester capacitors have positive temperature coefficients.

What determines the self-inductance of a film capacitor?

The self-inductance or series inductance LS of a film capacitor is due to the magnetic field created by the current in the film metallization and the connections. It is thus determined by the winding structure, the geometric design and the length and thickness of the contact paths.

How reliable are film capacitors?

The most important reliability feature of film capacitors is their self-healing capability, i.e. their abil-ity to clear faults (such as pores or impurities in the film) under the influence of a voltage. The metal coatings, vacuum-deposited directly onto the plastic film, are only 20 50 nm thick.

How does film shrinkage affect a capacitor?

Additional changes in the capacitor dimensions will follow as a consequence of film shrinkage. The absorption of moisture increases the number of permanent dipoles inside the capacitor, pro-ducing reversible effects on capacitance, dissipation factor and insulation resistance, which are treated in the respective sections.
